Zeitgeist was crap, in addition to getting a lot of facts wrong it was just poorly made, I'm talking "anyone on youtube could have copied and pasted it together" poor. Sure Michael Moore makes stuff up but at least he's a talented craftsman and entertainer. Zeitgeist is pretty much the bottom of the conspiracy nut barrell.
Anyway.
From my experience, many of the best documentaries are those that function as character studies rather than try to be educational or full of lectures.
Case in point. My favorite documentary.
This is required viewing for anyone that has aspirations of becoming a filmmaker, or better yet someone who understands from experience just how fustrating the process can be. It's about an amateur filmmaker and his friend who try to make a low budget horror movie so he can make enough money to fund a longtime pet project.
It's freaking hilarious, but surprisingly touching and inspirational at the same time. This is proof that documentaries can be just as funny and entertaining as fictional films if not more so. This movie should have gotten a best picture nomination. You can't help but love these guys.
I still can't watch these scenes without hurting myself with laughter.
